RE GE NERATIVE GAS-FURNACE Speocaton o Letters Patent.

Patented May l1, 1909.

To all whom it may concern:

Be it known that I, JOSEPH B. AcKER, a citizen of the United States of America, residing in New York, in the borough of Broeklyn, county of Kings, and State of New York, have invented certain new and useful Iniprovements in Regenerative Gas-Furnaces, of which the following is a specification.

This invention relates to an improved re generative gas-furnace for heating benches of gas-retorts. Heretofore gas-furnaces of this class were made of a certain depth correspending to the length of the retorts, two furnaces being preferably built so as to abut at their inner ends and tired at their outer ends by means of two separate fires.

The object of this invention is to construct a regenerative gasfurnace in such a manner that a bench of retorts ol greater than ordinary length is used, which is heated by one lire and attended to from opposite ends in such a manner that the air for combustion both for the fuel on the grate and for heating the retorts is supplied through the inductionopenings in the front and rear walls of the furnace and evenly and effectively distrib* uted. around the retorts, the opposite ends of the bench of retorts being heated by two systems of air-heating lues, one for one end and the other for the other end of the retorts; and for this purpose the invention consists of regenerative gas-furnace comprising a bench of retorts, a single gas-generating Vlire-place approximately centrally below the same, a

l. lateral bridge-blocks c1.

primary system of air-heating I'lues under the l grate toriacilitating the combustion of the l fuel in the fireplace, two secondary syst-eins of air-heating llues, one for heating one endportion ol' the gas-retorts and the other for heating the other end-portion ci the gasretorts, located at each side of the ireplace, and a series of draftdiues for drawing the hot gases around the retorts and then in downf Ward direction around and between the systems of secondary air-heatmg lues and under the system of primary air-heatinol llues to the chimney.

The invention consists further in a bench of gas-retorts adapted to be charged at opposite ends and provided with brace-blocks for supporting the same, and means for heating u the entire bench oi retorts and the braceblbcks, as will be fully described hereinafter and iinally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a front-elevation and a vertical transverse section of my improved regenerative gassfurnace, arranged sidewise of each other, Fig. 2 is a vertical longitudinal section on line 2, 2, Fig. l, Figs. 3, 4, 5 and 6 are horizontal sections drawn on dierent superposed planes, respectively on lines 3, 3, 4, t, 5, 5, and 6, 6, Fig. 2, and Fig. 7 is a vertical secticn on line 7, 7, Fig. l.

Similar letters of reference indicate corresponding parts throughout the several tigures.

Referring to the drawings, u, represents a gas-'generating fireplace which is arranged vertically below the combustioikchamber t. rlhe combustion-chainber is located above the fireplace c and is made Wider at its mid dle portion and contracted atits lower and upper ends, shown in Fig. l. lt is provided with a grate of suitable construction and an ashpit c1 below the grate. A stationary ashpan oZ is located in the ashpit, the ashes and clinhers being removed from time to time through the ashpit-door, which is located at one end of the lireplace. ln the side-walls of the fireplace are arranged a number of superposed air-heating lues, While above the air-heating llues and combustionchainber is arranged a bench of retorts 7', which are supported on top and bottom braceblocl s c located below and above the retorts, said brace-blocks being connected vertically above the comb ustion-chamber by The lowermost retorts '1" are supported on brace-blocks c2 which are formed ol two overlapping blocks, the cuter ones being inserted at their outer ends into the side-wall of the furnace and the inner ends into the recessed ends of the inner blocks c2, which orm at the same time the top-parts of the discharge-channels for the heated air delivered to the combustionchaniber from the air-heating ilues. The upper brace-blocks c rest by their outer ends on projecting bricks in the side-walls and abut by their inner ends against the bridgebloclrs c1. At suitable intervals throughout their length, the retorts are surrounded by side-blocks which are held in position by the brace-blocks and bridge-blocks, as shown in crosssection in VFig. l. The retorts '1 are open at both ends and made in sections olE suitable length, so that each full retort eX- tends throughout the entire furnace to a depth of twenty feet or more. Above each senese nace with its retorts is heated by one single ond, that by dividing,` the loneitudinal conl necting channels between the secondary airheating channels and the eduction-chamiels into two groups-a iront and rear groupand providing for each group separate secondary air-heatingl lues, the uniform heatingI el the retort-chamber and retorts by and a uniform distribi'ition ol the heated air from the conrbirstion-chamber through the retortchaniber and around the retorts is obtained; third, that by the arrangement of the bracebloclis lier sulinmrtingl the retorts in connection with the lnidge-blocks and abutting bricks and the stepped. blocks below the arch of the furnace, a very reliable and strong support for the retorts is obtained that permits the convenient removal ol worn-out retortsections and lrace-bloclrs and the renewal of the saine by new retort-sections and bracebloclrs; fourth, that by the accessibility of the gas-furnace from the iront and rear the air-heatingI lines Vand draft-nues can be conveniently cleaned by the usual openings and stoppers for the saine and, iifth, that by the construction described a gas-furnace is obtained which can be operated at a considerable saving' in time, labor and luel.

Having' thus described my invention, l claim as new and desire to secure by Letters Patent:
